Answer:
inverse of 5/42 = -42/5 = -8 2/5 = -8.4
inverse of 15/42 is flipped -42/5 = -2.8
The decimal steps are;
if 5/42 then show -1/1 = 5/42 = 42/5 = 8 2/5
= 8.4
if 15/42 then -1/1 ÷15/42 = -14/5
= -2.8
Step-by-step explanation:
if the question was 15/42 then we divide by -1 /15/42 = -42 / 15
so we can divide all by -1 or -1/1
The calculation steps are ;
-1/1÷ 15/42
= -1/1×42/15
= -1 × 42 / 1 × 15
= -42/15
The decimal steps are;
if 5/42 then show -1/1 = 5/42 = 42/5 = 8 2/5
= -8.4
if 15/42 then -1/1 ÷15/42 =–14/5
= –2.8
